Final answer:
The Niobides Krater is exceptional due to its incorporation of elements of wall paintings, use of the red-figure technique which allowed for detailed and complex compositions, and because it is crafted from clay, a testimony to ancient Greek artistry.
Step-by-step explanation:
Exceptional Character of the Niobides Krater
The Niobides Krater is exceptional for various reasons, one of which is that it incorporates elements of wall paintings. This is evident in the complex compositions and the numerous figures featured on it, resembling the narrative style of larger frescoes. Secondly, it's significant because it's made of clay, which was a common material in Greek vase-making but continually impresses with the level of artistry achieved with such a humble material. Moreover, this krater is painted using the red-figure technique, a significant development in vase painting during the ancient Greek times. This technique allowed for greater detail and a more realistic representation of the human body and other elements, compared with the earlier black-figure style. Finally, the vase is noted for its elaborate scenes that feature many figures, which indicate an evolution in Greek art toward more dynamic and intricate storytelling.
The use of the red-figure technique is distinguished by its figural depictions in red color on a black background. Unlike the black-figure style, the red-figure technique afforded artists more flexibility in rendering details, as seen in the works of notable painters like Euthyides and Euphronios. This enabled them to depict space, movement, and naturalism with an unprecedented level of sophistication for the time.
